I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. Show object's name in "object reference not set to an instance of an object" exception.

    It's really hard to debug such errors and find which variable/object is null.

    • Allow custom marshaling on arrays in structs

      For some reason, you can't use the MarshalAsAttribute with UnmanagedType.CustomMarshaler on an array when the array is inside a (sequential layout) struct. The IDE and compiler don't complain, but it will always throw an exception at runtime. This makes it bizarrely difficult to solve problems such as this one: http://stackoverflow.com/questions/5902103/how-do-i-marshal-a-struct-that-contains-a-variable-sized-array-to-c; you have to put the MarshalAsAttribute on parameters of array types (rather than putting it *inside* a struct once, and having the struct contain the array type) and consequently you lose the ability to do things like custom constructors, etc. for your array type.

                      • Add a way to Get the Progress percentage of Extracting a zip file in System.IO.Compression.

                        Currently I cant Update a Progressbar with percentage (unlike with downloading) when Extracting a zip file. I would like to make this possible below.
                        ```cs
                        ZipArchive zar = ZipFile.OpenRead(Application.StartupPath + "\\ILSpy_Update.zip");
                        /*
                        Not Sure how I can get it to fill the Progress bar. I think I would need some help here on this part.
                        */
                        zar.ExtractToDirectory(Application.StartupPath + "\\Update\\");
                        zar.Dispose()```

                        • TPL async task.ConfigureAwait() should have option to inherit the stack trace from original thread

                          When we await an async task, the continuation Thread does not appear to inherit the call stack from the originating Thread. This causes us problems when we use the System Diagnostics Tracing as the call stack does not represent the logical flow throw the application.

                          • WebBrowser. Compatibility Mode Edge by default

                            The WebBrowser control should run in edge mode by default or at least let us control this in the browser through a property. By default the browser seems to be running in IE 7 compatibility mode and most new websites do not render correctly.

                            From what I can tell the options to correct his are:
                            Insert tags in the web pages. This is impossible as I don't control the internet. Change a registry key, also impossible as click once setup does not allow this.

                            • CRC32 Helper Class

                              Many applications that communicate with low-powered hardware need a way to verify the received data. CRC32 is a well-known, lightweight check value which is better suite to verify short data.

                              .Net already has an implementation of this check value with (System.IO.Compression.Crc32Helper, System.IO.Compression, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089) but this class has an internal ac cess modifier and can't be used by user code.

                              My proposition is to make the Crc32Helper class public.

                              • Create an extension to take desktop apps to the Windows Store

                                Instead of telling people that have to use a console application to convert desktop apps for the Windows Store, why didn't anyone in Microsoft think "Why don't we use Visual Studio?".

                                You have the best development tool on the planet, and you give me instructions with no documentation on using a desktop app converter console application.

                                Desktop applications is Microsoft's best platform, and you consistently make it a third class citizen behind UWP and web Asp.NET.

                                If you have a tool that does the code, building this with a GUI should be simple.

                                • Sepcify table name for multiple recordsets

                                  When you return multiple recordsets from a store proc, it will be nice if we can specify the custom table name for each record set and access the tables via table name than index. In this way code can be dynamic and lot easier. The current hack is provide one extra table for recordset to table name but it is not neat. Depending on the index and prior knowledge can cause lot of bugs.
                                  The following should be done
                                  1) When multiple recordsets are returned from the storeproc, the SP developer can tag each recordset with a table name (ex:…

                                    Sometimes we use clases that are not in the intelligence and not in our namespace. Why don't white it with help of the intelligence and auto import it

                                    • Linq - add, update, delete statements

                                      I think it would be simple the idea to add, update and delete objects based on the Enumerator<T>
                                      C# Example

                                      Insert into:
                                      var i = 0;
                                      var a = from d as MyType in MyEnumerableType
                                      where d.IdProp = 1
                                      insert new MyOtherType(i++,d.IdProp,d.Prop1) {Prop2 = d.Prop2} into MyOtherEnumerableType; //-> performing over the enumerator of both objects

                                      Update:
                                      var i = 0;
                                      var a = from d as MyType in MyEnumerableType
                                      where d.IdProp = 1
                                      set d.Prop1 = "Value different than before", d.BooleanProperty = False

                                      Delete:
                                      var a = from d as MyType in MyEnumerableType
                                      where d.IdProp = 1
                                      delete d; //->…

                                      • microsoft help viewer (Microsoft.AspNet & System.Web.MVC)

                                        Where should I find MVC documentation ?
                                        There is no documentation for Microsoft.AspNet, System.Web.MVC.

                                        Update Microsoft Help Viewer 2.2 for ASP .Net, MVC, Entity Framework (EF), .Net Core. Not All your customer likely to connect internet all the time. Suppose, They think want to save energy offline will be the only solution for laptop's battery.

                                        If you ignore your support for developers, they will also abandon M$ product.

                                        • Auto-create Controller Actions from data entered into JavaScript/JQuery Ajax methods

                                          A great feature of many IDEs, including VS, is that you can define a function on the fly and automatically create a method stub for it.

                                          Wouldn't it be great if this could be done when you are making Ajax requests to the server?

                                          For example, say you wish to send data to an action using JQuery's $.post() method:

                                          You type $.post("MyController/MyAction", {data: "myData"}); into your front-end code, this new feature would then give you the option to auto-create an action "MyAction" in controller "MyController" with a string paramater "data" and a default return type of say, ActionResult.

                                          I'm still…
